3 Pairs of North/South Neodymium Countersunk Magnets - D20mm x 7mm
Same Day Dispatch
Order before 1pm to qualify for same day dispatch.
This magnetic holder is made for fastening various metal objects. It includes a small metal cup with a neodymium rare earth magnet and a central hole for surface attachment. Simply screw it onto non-metal surfaces and use it to easily organize and secure your tools. It's perfect for holding kitchen utensils, gardening tools, and mechanical or handyperson tools. The magnet keeps metal objects in place and can be easily removed or replaced. This practical and easy-to-use magnetic product can be attached to wooden surfaces with an appropriate screw.
This set includes 6 pieces of countersunk magnets, with 3 featuring a North polarity and 3 featuring a South polarity.
IMPORTANT NOTES:
According to expert analysis, these Neodymium magnets have a holding force when directly in contact with mild steel that is 10mm thick or thicker. The specified force is based on horizontal holding, assuming a minimum steel surface thickness of 3mm. If the magnet is positioned vertically, the holding force should be divided by 3 due to the effects of gravity and reduced friction.
AVOID:
When attaching these magnets, keep in mind that magnetic strength may be reduced if the surface is made of alloy, stainless steel, Colourbond steel, or if it is painted, oily, rusty, or bumpy. Additionally, thinner ferrous items such as foil or sheet metal may result in a weaker magnet pull. If there is any material between the magnets and the attaching surface, such as fabric, the pull strength will also be diminished.

Surface Treatment
The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.
Range and Tolerance
Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.
Magnetic Properties
Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
